FPGA implementation of the race-control algorithm for the full-bridge passive resonant commutated poles converter

The inedited race control algorithm (RCA) for full-bridge passive resonant commutated poles (FB-PRCP) is presented and implemented with FPGA technique. It enhances the basic control algorithm of that topology allowing quicker responses, like those required by welding applications, as manual metal arc welding (MMA), in which very fast duty cycles dynamics are required. The effectiveness of the RCA have been experimentally tested on a true converter.
